This is the best upgrade you can make on your PX-4. I own 2 one in 40 S&W and a new purchase in 9 mm. Both compacts. Since both guns weigh 27.2 I purchased the 9 mm to take advantage of the reduced recoil. The trigger group was simple to install, even without instructions. It really made a tremendous difference. I used an #11 Wilson chrome spring it is averaging 3.43 single action. It's so slick and fast you must watch out or you will double tap before you know it. I am using this 9 mm for competition. I love It! Every edge you can get helps.
